  • Publication number: 20240132063
    Abstract: A driving support apparatus comprises a sensor configured to detect an object, and a controller configured to execute a collision control when the object satisfies a first collision condition. The controller determines whether or not the object satisfies a second collision condition which is more difficult to be satisfied than the first collision condition when both an angle condition and a steering condition are satisfied in a case where the object is a three-dimensional object which is in a roadside or a median strip of a road. The angle condition is a condition that an entry angle formed by a traveling direction of the vehicle and the three-dimensional object is equal to or smaller than a threshold angle. The steering condition is a condition for determining that a driver performs an avoidance steering operation. The controller executes the collision control when the three-dimensional object satisfies the second collision condition.

  • Publication number: 20240123671
    Abstract: A temperature adjustment mold capable of performing local temperature adjustment in an axial direction from the inside of a preform while restricting shrinkage and deformation of the preform, for adjusting a temperature of an injection-molded bottomed resin-made preform includes a rod portion inserted into the preform and extending in the axial direction of the preform. The rod portion includes an annular projection portion that protrudes in a radial direction of the rod portion and contacts an inner peripheral surface of the preform. The rod portion contacts a bottom portion of the preform to restrict shrinkage in the axial direction of the preform. The projection portion restricts shrinkage in a radial direction of the preform, conducts heat between the rod portion and the preform, and adjusts a temperature at a predetermined part in an axial direction of the preform.

    Abstract: Disclosed is a driving assistance apparatus which includes an object information obtaining section for obtaining a piece of information regarding an object present ahead of a vehicle, an operation amount obtaining section for obtaining an accelerator pedal operation amount, and a control section. The control section predicts whether or not the vehicle will collide with the object on the basis of the obtained object information and executes collision avoidance assistance control for decelerating the vehicle at a predetermined demanded deceleration rate in the case where the control section predicts that the vehicle will collide with the object and an execution condition becomes satisfied as a result of the obtained accelerator pedal operation amount having become equal to or greater than a predetermined operation amount. The control section sets the demanded deceleration rate on the basis of the distance and the relative speed obtained when the execution condition becomes satisfied.

  • Publication number: 20230192083
    Abstract: A driving supporting apparatus comprises an acceleration operation element operated by a driver; and a control unit capable of performing an acceleration limiting control to control the vehicle in such a manner that an acceleration of the vehicle does not exceed a predetermined limiting acceleration. The control unit sets a distance threshold to a value varying depending on a kind of a front target object that is present in front of the vehicle, and performs the acceleration limiting control when a distance condition and an erroneous operation condition are satisfied. The distance condition is a condition that is to be satisfied when a distance between the vehicle and the front target object is equal to or shorter than the distance threshold. The erroneous operation condition is a condition that is to be satisfied when the driver is erroneously operating the acceleration operation element.

  • Patent number: 11643075
    Abstract: In a case of a mistaken pedal operation determination: ON, the driving assist ECU sets a value of a steering angle threshold ?ref to a value ?ref2 which is greater than a normal value of the steering angle threshold, and sets a value of a steering operation rate threshold ?ref to a value ?ref2 which is greater than a normal value of the steering operation rate threshold. When a steering angle ? is equal to or greater than the steering angle threshold ?ref and/or when a steering operation rate ? is equal to or greater than the steering operation rate threshold ?ref, the ECU delays a start timing of a automatic brake control, by setting a value of a threshold for executing TTCa to a delaying execution threshold TTCa2 that is smaller than a normal value of the threshold for executing TTCa.

  • Patent number: 9491096
    Abstract: A switching process includes an SRAM/CAM storing registration data including a forwarding database used for packet-forwarding and a DRAM storing packet data. The registration data including the forwarding database of the SRAM/CAM for packet-forwarding is stored into the DRAM as a copy of the registration data, and the registration data of the DRAM is used to refresh the registration data of the SRAM/CAM for a predetermined time interval. A data error in the SRAM/CAM caused by a soft-error is rewritten to normal data by periodical refreshing so that data is guaranteed with relatively low cost and the reliability of the network apparatus is improved.

  • Patent number: 9047416
    Abstract: In a switching node, high-speed and advanced service protocol processing function is achieved by utilizing an external control server without affecting performance of conventional service protocol processing. Specifically, a forwarding engine has PCI express and an LAN interface. Depending on a type of an input packet, destination of the packet is switched to the PCI express side for conventional network service and to the LAN interface side for extended network service that cooperates with the external control server. A CPU having the PCI express and the LAN interface is provided ahead of the LAN interface. The CPU performs communication of service inquiry with the external control server at high speed via the LAN interface. After response from the control server is obtained, setting of the forwarding engine is performed through the PCI express.

  • Patent number: 7787635
    Abstract: Resonant frequencies f2 and f3 detected in a resonant space are determined as center frequencies of a dip. Based on measurement values at a speaker and a microphone in the resonant space, a basic amplitude frequency characteristic Ca and a target amplitude frequency characteristic Cd are found. A smoothness degree on a frequency axis is larger in the target amplitude frequency characteristic Cd than the basic amplitude frequency characteristic Ca. A damping level and quality factor of the dip are determined based on a difference between the basic amplitude frequency characteristic Ca and the target amplitude frequency characteristic Cd in the center frequencies f2 and f3 of the dip and frequencies near the center frequencies.
